Title: Image forming device
Inventor: TAKAGI YASUSHI
IPC: G03G15/04
Filed: 1987-09-01
Abstract: PURPOSE:To prevent the damage of document and to eliminate the waste of an operating time by detecting whether the document is left or not, driving an automatic document feeder if the document is left and ejecting the document. CONSTITUTION:The detection of the left document is performed with a density detection sensor and a size detection sensor and the existence of the document is judged according to the output value and output difference from both sensors. It the document is left, an ejection sensor installed in the ejection roller part of a document feeder DF detects it and drives the DF so as to perform the ejection process of the left document. When the ejection process is performed, the DF is drive again to feed in the document which is going to be copied. Thus, the damage and the rimple, etc., of the document can be prevented in case where the document is fed in by using an automatic document feeder ADF without noticing the left document.

Title: Wiring delay time excess alarming device for large scale integrated circuit
Inventor: MARUI TOMOTAKA
IPC: H01L21/82
Filed: 1989-08-24
Abstract: PURPOSE:To quickly perform wiring design by issuing an alarm at the time when the minimum delay time of a wiring path in the middle way of the wiring design exceeds the maximum allowable delay time inputted in advance. CONSTITUTION:The minimum delay time TD(min) of the wiring path is computed while performing the wiring design with a minimum delay time arithmetic means, and computed TD(min) is compared with the maximum allowable delay time TD inputted in advance with a comparison means, and when the TD(min) exceeds the TD as the result of comparison, the alarm is issued from an alarming means. A designer can recognize that the wiring path in the middle way of generation at present is an inappropriate one incapable of supplying desired signal propagation speed. Therefore, the wiring design is stopped at a stage when the alarm is issued, and the wiring design is performed again, thereby, time and labor to perform the wiring design from the beginning after it is completed can be evaded. In such a manner, the wiring design itself can be accelerated.

Title: Ferroelectric liquid crystal element
Inventor: YOSHINO KATSUMI
IPC: G02F1/137
Filed: 1986-09-16
Abstract: PURPOSE:To obtain an optically functional element having great contrast, good visual angle characteristics to be used for light switch control, light memory, or recording element by utilizing the change of light scattering and light transmission characteristics caused by transferring both of the helical condition of a liquid crystal and the released condition of the helical state to each other. CONSTITUTION:A cell is prepd. from rubbed transparent electro-conductive glass plates, and a ferroelectric liquid crystal is sealed therein. The temp. dependency curve of the light transmittance of the cell forms a hysteresis curve in the ferroelectric liquid crystal phase. The high transmission state A of the hysteresis curve corresponds to the loosened state of the helical molecule, and the low transmission state B of the hysteresis corresponds to the wound state of the helical molecule. For example, when 50Hz, 3V Ac is applied, the molecule is transferred from the state A to B. When the pulse of the AC voltage is 600Hz, the molecule is transferred in a moment at ca.10V to the state B, which is continued even after the impression of AC pulse is suspended. Further, when 10V DC is impressed stepwise in the state B, the molecule is transferred to the state A in a moment, and the state is retained for a long time after the impression is suspended. Thus, a memory effect is obtd.

Title: Optical sensor
Inventor: KISHIDA JUICHI
IPC: H01L31/09
Filed: 1985-10-02
Abstract: PURPOSE:To improve the reliability of electrical connection with external elements, by forming an amorphous silicon photosensitive semiconductor before forming a lower or upper electrode connecting portion of a plurality of metal layers. CONSTITUTION:A lower electrode layer 2a of chromium is formed on the whole surface of a transparent and high-resistance substrate 1, and an amorphous silicon layer 3 is deposited in a required place thereon. Then an upper electrode layer of indium tin oxide 4 is formed, and a silicon nitride layer 5 is provided. Subsequently, a nickel-chromium alloy layer 6 and a gold layer 8 are formed. Unrequired portions of the gold layer 8 are removed for forming an electrode connecting portion 10. Unrequired portions of the nickel-chromium alloy layer 6 are also removed for forming a nickel-chromium wiring layer. In such construction, since the amorphous silicon layer 3 is not contacted with the gold layer 8, the characteristics of an optical sensor 20 thus produced can be substantially increased. Further, since there is no need of performing a heating process after the formation of the gold layer 8, the loss of the gold layer 8 due to diffusion can be avoided.
